Episodic Cost of Lower Respiratory Tract Illness due to Respiratory Syncytial Virus Among US Infants During the First Year of Life

A study of 2 health care claims databases (commercial, Medicaid) was undertaken to estimate the episodic cost of lower respiratory tract illness due to respiratory syncytial virus among infants aged <12 months overall, by age, and by birth gestational age. Among commercial-insured infants, mean costs were $28 812 for hospitalized episodes, $2575 for emergency department episodes, and $336 for outpatient clinic episodes. Costs were highest among infants aged <1 month and infants with a gestational age <= 32 weeks and were comparable among Medicaid-insured infants, albeit somewhat lower. The cost of lower respiratory tract illness due to respiratory syncytial virus during the acute phase of illness is high, especially among the youngest infants and those born premature.
